Imajourn turns sound into shape: water that sings, sand that gathers on a ringing plate, and sound travelling through a room in 3D. Hum a note or touch the water and watch the pattern form. Free on iPhone and iPad; Pro is one purchase. No ads, no tracking.

Imajourn is an interactive simulation sandbox that brings the physics of waves and sound to life. Whether you are an artist, a physics enthusiast, or a meditator, Imajourn offers a mesmerizing playground of light, motion, and geometry. Imajourn has moved from its early open source webapp version (Numatics) to a fully functional App Store app with new name and branding, and many new features: Interactive wave sim, chladni patterns and cymatics, audio reactivity, 3D particle sim, presets and more!
